THEMIS Image of the Day, May 3, 2017. Today’s false color image shows part of Sirenum Fossae. The linear depressions in this image, called graben, were formed by tectonic activity. The THEMIS VIS camera contains 5 filters. The data from … Continue reading →

THEMIS Image of the Day, May 2, 2017. Today’s false color image shows part of Gorgonum Chaos. Chaotic regions form when groundwater escapes to the surface, undermining it and causing the ground to collapse. The linear depression at the bottom … Continue reading →

THEMIS Image of the Day, April 14, 2017. Today’s false color image shows a section of Tempe Fossae located in Tempe Terra. This is a graben that formed when subsurface forces pulled the ground apart, and a portion of the … Continue reading →

THEMIS Image of the Day, February 8, 2017. Today’s false color image shows part of the plains of Thaumasia Planum. The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create … Continue reading →

THEMIS Image of the Day, January 13, 2017. Today’s VIS image shows graben called Claritas Fossae. These are caused when the ground is pulled apart, and the land between parallel faults drops down. More THEMIS Images of the Day by … Continue reading →

THEMIS Image of the Day, January 12, 2017. The linear depressions in this VIS image are graben. Graben are formed from tectonic activity with large blocks of material moving downward between paired faults. The crater in the bottom half of … Continue reading →

THEMIS Image of the Day, January 3, 2017. Today’s false color image shows part of Gorgonum Chaos. The linear features are tectonic faults, called graben, that are part of Sirenum Fossae. The THEMIS VIS camera contains 5 filters. The data … Continue reading →

THEMIS Image of the Day, December 8, 2016. The channel-like features in this VIS image are tectonic graben. The graben (called Icaria Fossae) are located in Terra Sirenum. The graben are caused by tectonic forces that faulted the bedrock, allowing … Continue reading →

THEMIS Image of the Day, November 29, 2016. Today’s VIS image shows part of Sirenum Fossae, a large graben on the margin between Terra Sirenum and Daedalis Planum. Grabens are formed by the downward movement of material between parallel tectonic … Continue reading →

THEMIS Image of the Day, November 28, 2016. Today’s VIS image shows a small portion of Noctis Labyrinthus. Noctis Labyrinthus is a network of tectonic graben and collapse valleys on the western margin of Valles Marineris. More THEMIS Images of … Continue reading →
